Example Embodiment

[0022] Attached below figure 1 The present invention will be further described in detail with specific embodiments:

[0023] A power plant condensation heat recovery and utilization and heating system, such as figure 1 As shown, it includes a steam pipeline 1, a circulating cooling water pipeline 2, an air extraction pipeline 3, a backup circulating cooling water pipeline 4, and a heating pipeline 5.

[0024] The steam in the steam pipeline 1 is sent to the steam turbine 11 to perform work, and the exhaust steam discharged after the steam turbine 11 performs work is sent to the condenser 12, and the exhaust steam passes through the condenser 12 to transfer heat energy to the cooling water in the circulating cooling water pipeline 2. Then it condenses into water and discharges.

[0025] The steam extraction pipeline 3 is provided with an absorption heat pump 7 and a steam-water heat exchanger 6. The steam in the extraction pipe 3 drives the absorption heat pump 7 to absorb heat, an...

Abstract

The invention relates to a heat recycle system, and discloses a condensation heat recycle and supply system of a power plant. The system comprises a steam pipeline, a circulating cooling water pipeline and a heat supply pipeline. The system is characterized in that the heat supply pipeline is branched into a heat pipeline and a boiler water feed pipeline after passing through an absorption type heat pump, and the heat pipeline is conveyed into a heat supply network through a steam-water heat exchanger to form a loop; and the boiler water feed pipeline is connected with boiler feed water. Condensation heat recycle is realized through heat exchange of the absorption heat pump, condensation heat of the power plant is recovered, and an emergency heat supply system is arranged, so that the condensation waste heat of the power plant can be recycled in winter and summer. The system has the advantages of high heat energy recycling rate, energy conservation and emission reduction and the like.

Description

technical field [0001] The invention relates to a power plant waste heat recovery device, in particular to a power plant condensation heat recovery and utilization and heat supply system. Background technique [0002] The condensation heat of thermal power plants is discharged into the atmosphere through cooling towers or air-cooled islands, resulting in huge heat loss, which is the main reason for the low efficiency of energy use in thermal power plants. It not only causes a lot of waste of energy and water or electricity, but also seriously pollutes the atmosphere. . The evacuation of condensation heat in thermal power plants is a common problem in our country and even in the world. It is a waste and helpless. However, with the development of heat pump technology, especially the advent of large-scale high-temperature water source heat pumps, it will become possible to recover the condensed waste heat of generating units. Contents of the invention [0003] Aiming at the...
